USB 3.0 ports do not see external hard drive

The laptop has three USB 3.0 ports and one USB 2.0. When you attach an external hard drive WD with USB 3.0 to the USB 3.0 ports the notebook does not see it. If attached to the same screw to a USB 2.0 port, everything is normal.
Thus, the same external hard Transcend with USB 2.0 interface, USB flash drives and other USB devices see each other fine on all 4 ports.
Nobody knows how to cure it?

Laptop: HP envi m6 Intel Core i5, mother - HP18A5, Win8.
Problem the screw: WD 1 TB 2.5" without external power (firmware last).

Little data for any of the versions. Have you updated BIOS, did all the wood cost on USB 3.0 controller, what mode the controller in device Manager, the WD is also not seen?

Formatting the hard drive might help, but if it's full, it is an extreme version, as it will take time and will need a place where to move the data. And the way could it be to blame for example the file system on the screw?

Like in power settings there is a ban on power off USB or something like that. It on computers with USB 3.0. Maybe the problem is in the food?

I had a similar problem with an Adata SSD that had sata and usb3.0 the side. in USB2.0 in any computer, worked, and USB3.0 first worked and then suddenly stopped. although he only worked at usb 2.0. I just merged the data with him, and passed into the store as second, for two weeks only passed before it started, it was just a year and a half ago, I suspect the controller u disk canal treatment usb3.0 poorly protected transceiver LVDS from static electricity, I think this sin all the controllers that put in the disks of the time, now like never met the 3 drives and one WD pasport 2TB usb3 c.0.

And a screw is at least somewhere working on 3.0?

Plug USB3.0 has a complex structure, for compatibility with the standard 2.0 first check with another cable.
